[5 7] ABSTRACT An anti-pollution device for insulation in factory smokestacks. This device includes a charcoal filter through which the smokeis pulled by fan blades.

The device also includes high voltage electrodes for producing an arefrom point to point which is accomplished by a distributor.

4 Claims, 2 Drawing Figures ANTI-POLLUTION APPARATUS This inventionrelates to air pollution control devices, and more particularly to ananti-pollution apparatus for smoke stacks.

It is therefore the primary purpose of this invention to provide ananti-pollution apparatus which will greatly lessen the outpouring ofsmoke and noxious gases from smoke stacks.

Another object of this invention is to provide an antipollutionapparatus which will include a charcoal filter within the smoke stackthrough which is pulled the smoke by means of a plurality of motordriven fan blades, the charcoal filter serving to remove the toxic gasesand smoke particles.

A further object of this invention is to provide a first means oftreating the smoke before it is passed through the charcoal filter, thefirst means being a plurality of spaced apart electrodes from which ahigh voltage spark is produced from point to point by means of adistributor which causes the electrodes to fire alternately.

A further object of this invention is to provide an apparatus of thetype described which will have the interior of the smoke stackaccessible by means of a door in order to service the motors and fanblades therein.

Other objects of the present invention are to provide an anti-pollutionapparatus which is simple in design, inexpensive to manufacture, ruggedin construction, easy to use and efficient in operation.

These and other objects will be readily evident upon a study of thefollowing specification and the accompanying drawing wherein:

FIG. 1 is a vertical view of the present invention shown in section; and

FIG. 2 is a fragmentary view similar to that of FIG. 1, but showing amodified form which includes water spray means for removing the smokeparticles, the water being carried into a sediment collector devicewhich allows removal of the particles and the water can be recirculatedby pump means to the spray nozzles.

According to this invention, an anti-pollution apparatus is shown toinclude a common smoke stack 11 having a smoke inlet 12 at its lowerextremity, the smoke entering through the stack wall 11 A charcoalfilter 13 extends across the entire air diameter of stack 11, the filter13 being supported upon the screen 14. A plurality of spaced apartelectric motors 15 having fan blades 16 are supported upon mountingbrackets 18 which are secured fixedly to the interior of wall 11'.

The rotating fan blades 16 provide a means of pulling the air throughthe charcoal filter 13, the filter l3 serving to remove the noxious gasand smoke particles from the smoke.

It will be noted that an opening 19 through wall 1 l is covered by ahinged door 20, the arrangement allowing for the motors l5 and the fanblades 16 to be serviced.

A stairway 21 secured to the outer extremity of wall 11, allows for theworker to ascend stack 11 in order to reach door 20. An electric motor22 is provided with a cable 22' which is connected to a power source andmotor 22 rotates the distributor 23.

The wires 24 extending from distributor 23 are secured to the highvoltage transformers 25 which are mounted to posts 25'.

The output of transformers 25 are secured to the electrodes 26 which aresecured fixedly to wall 11 of stack 11, the electrodes 26 serve to causea high voltage electric arc for further purifying the smoke.

Looking now at FIG. 2 of the drawing, one will see a modified apparatus27 similar to that described in the main embodiment of the presentinvention.

Apparatus 27 has an additional method of further cleaning the smoke byhaving a plurality of nozzles 28 which produce a fine spray, the nozzles28 being supplied with water by means of a pump 29 which is driven by amotor 30.

The water from nozzles 28 serve to collect the smoke particles which bygravity means, will fall into the annular sump 31, the water thencarrying the smoke sediment by means of pipe 32 to the sedimentcollector 33 wherein the water is then recycled through the pump 29 andback into the nozzles 28.

It will be noted further that the smoke particles, by gravity means willsettle in the bottom of sediment collector 33 and the clean water willbe taken off at the upper extremity of sediment collector 33 by means ofthe water pump 29.

What I claim is:

1. An anti-pollution apparatus for smoke stacks, comprising, a verticalsmoke stack, a plurality of motor and fan blades carried within saidstack providing a means of pulling air up through said stack, a charcoalfilter carried within said stack providing purifying means for the gasesbeing pulled through said stack, support means for said filter carriedwithin said stack, a plurality of electrodes carried by said stack forproducing an intermittent electric are, high voltage transformer meanscarried by said apparatus with distributor and motor means foralternating the arcing within said stack.

2.

3. The combination according to claim 2, wherein said fan blades aresecured to electric motors that are fixedly secured and spaced apart onthe interior of said stack and a partial vacuum is created in order topull said air through said charcoal filter, said charcoal filter servingto remove the noxious gases and smoke particles from said air beingdrawn through said stack and said high voltage electrodes serve tofurther break up said smoke particles and to purify said air, saidcharcoal filter being the final purifying element which will causesubstantially clean air to be egressed from said stack.

4. The combination according to claim 3, wherein repair of said motorsand said fan blades within said stack is accomplished by a workerascending stairs secured to the wall of said stack, said workman havingaccess to said motors by means of a hinged door secured to said stack,said hinged door covering an opening through said wall of said stack.
